Ubuntu PHP致命错误：无法重新声明类PHP\u CodeCoverage\u筛选器

我刚刚安装了PHP CodeCoverage pear包，现在当我尝试运行测试用例时，它给出了这个错误，我将把堆栈跟踪放在下面以了解更多细节；我使用操作系统ubuntu 12.04LTS

PHP Fatal error:  Cannot redeclare class PHP_CodeCoverage_Filter in /usr/share/php/PHP/CodeCoverage/Filter.php on line 58

这里有一个类似的问题：请告诉我这是否是您搜索的内容，以及该解决方案是否对您有效。我遵循了那里给出的说明，但现在没有运气，它给出了以下错误；PHP警告：require_oncePHPUnit/Runner/Version.PHP:无法打开流：没有这样的文件或目录您是如何安装phpUnit的？通过梨？还是每个项目都有一个本地版本？如果它是全局的，您只需重新安装它：sudopear卸载phpunit/phpunit sudopear安装phpunit/phpunit
